Walking into the community, people can see the hanging environmental slogans(环保标语) at first sight. And the most eye catching items are idle bins(闲置物品投放箱) around. Many people in the community would give their idle things into the bins. Xu Juan, a mother of two, once put a pair of gloves there. She said, “I think it's meaningful to help others.”
In order to encourage more people to join in the “low carbon” activity, the community introduced a reward program. Anyone can get some points if he/she gives idle things or takes part in volunteer activities. With certain points, people can exchange things in the “low carbon supermarket” in the community.
There is also an “exchange corner” in the community. People can exchange their idle things(except the living things) with others. If he/she is not interested in any idle things in the corner, he/she can donate his/her things to poor families in the community.
“We are trying to make the best use of idle things by free exchange and donation. We hope all the people in our community can live a low carbon life，” said Wang Lu, leader of Hanbei Road Community.

Today I'm here to talk about noise pollution. Not all noise is noise pollution. Noise becomes noise pollution when it's loud, when it's not necessary and when it begins to harm human and animal life.
Examples of noise pollution include the sounds of cars, buses, lorries, trains and planes. When you stand near a busy road, sometimes the noise can hurt your ears. And people living near airports often find it difficult to sleep. Noise pollution can also be from machines. We often use very noisy machines around the house or at our jobs. Factory noise is also a big problem. Finally, sometimes, loud music can be a form of noise pollution. For example, the music from a club or from your next door neighbour.
We must think that noise pollution is just a small problem, but actually it can be dangerous. Some people have become deaf because of noise pollution. What's more, when people lose sleep because of noise pollution, they become careless. This can lead to accidents, and people can get hurt or even killed. Finally, noise pollution makes people feel stressed, which can lead to heart disease.
What can we do about the problem of noise pollution We need stronger laws against loud noises. The government also needs to put up walls next to roads and airports to protect people from noise. Finally, we can all help with the problem of noise pollution by turning down our music and TVs, and using a softer voice when we talk.
1. Noise becomes noise pollution when ________.
A. it's low enough for people to hear
B. it's necessary to be loud
C. it begins to harm human and animal life
D. it comes from your earphone

4. We can all help with the problem of noise pollution by ________.

April 22nd is Earth Day—a day to remind people to protect the earth. So on that day, our family held an activity “Bottle of Trash Challenge”. That means the trash needs to be put in a 600 ml bottle. We decided to challenge ourselves and produce as little trash as possible.
My father worked online all day, so he didn't produce any paper waste except paper napkins. He made the least trash in our family.
My mother cooked and produced plenty of kitchen waste, such as vegetable leaves, eggshells and food bags. What's worse, we couldn't eat up all the food of the dinner that day. So leftovers couldn't be avoided. It was not easy for Mum to deal with all the trash, but she found a way to put it all into the bottle. How amazing!
My sister, a 16 year old student, was busy preparing for her exams. She had to use paper to work out Maths or Physics problems. She used only one side of the paper in the past. But that day, she tried to use both sides of the paper because she realized we were challenging ourselves. She did a good job!
I was different from my sister. I love snacks and drinks. So my trash was almost from them. I was highly alert(警觉的) that I must produce less waste. I hardly ever had snacks or drinks. It was too difficult, but I did it!
I've learnt a lot from this activity. I realize that everyone can produce less trash. We should start with small actions to protect the earth!
1. What activity did the writer's family hold on April 22nd

What does it mean to be green Green is more than just a color. It also means taking special steps to protect the environment. Buying a green product is a small step everyone can take. Deciding whether a product is green, however, isn't always easy. We need to consider the whole life cycle of the product, even after it's of no use. Here is what we may keep in mind.
The materials of a product are usually our first focus. What is it made of Are there any harmful chemicals in it Green products are made of more natural materials which are free from harmful chemicals, so they can be good for our physical health.
Packing is important. How is a product packed Is it overpacked We'd better choose glass, metal and paper packing, as these can be reused or more easily recycled. We can also look for less packing or even choose unbagged products whenever possible.
Location matters. Where was a product produced Where are we buying it Think about how much energy was used to get it to us. Try to choose local products. When it comes to food, it is a good idea to order directly from local farmers, shop at markets and buy fruits in season. Buying from stores near our houses is also a good choice, because we can go there without driving a car.
Look into what the company tells us about their product. It's easy to say that a product is “green” or “all natural”， but the words may be too good to be true. So, much of the information about a product should be taken with a grain of salt. After all, companies try to make us believe that their products are environmentally responsible.
The greenest thing is certainly the one we don't buy. Things like food and clothing are necessary for life. But many others are not. Better than buying is choosing to leave an unnecessary product in the store. It sends a message to the producer, keeps money in our pockets, reduces waste and keeps the planet healthy.
1. What do we know from Paragraph 1
A. Green is just a kind of color.
B. Green also means taking actions to protect the environment.
C. Deciding if a product is green is easy.
D. It is a big step to buy a green product.
2. What is talked about in Paragraph 2
A. Why we first focus on the materials of a product.
B. What green products are made of.
C. How a product is packed.
D. Where a product is produced.
3. According to the writer, we should choose a product that is ________．
A. made of unnatural materials B. produced abroad
C. locally produced D. overpacked
4. What is the best title for the passage
A. Reducing Energy Use B. Keeping Healthy
C. Recycling Waste D. Buying Green
